What are good abilities to buy using the Rubies? I started doing both the Dream dungeons and the Torment Dungeons(I can master the 1st torments pretty easily it seems, but the 2nd level of them are giving me conniption fits). I got the passionate Salsa since it seems to be a stronger multi-break with the added benefit of a mild cure, and the Fire thief ability that heals you via a portion of the damage you do, but beyond that, I'm just not sure, and really don't want to waste my record rubies on junk.

It kinda seems that the Black Mage 5 hit chain spells, and the Spellblade 5 hit abilities are probably ones that I can skip, just feels like a minor improvement that would just waste a limited resource.

So, yeah, some advice would be much appreciated on this subject :).
